Universal Orlando on Wednesday began testing the use of metal detectors for roller coaster passengers to ensure rider safety, according to the theme park.

The park said one metal detector was put into use Wednesday morning at the Hollywood Rip Ride Rockit coaster at Universal Studios. If the test runs smoothly, the park said it will consider putting stand-alone detectors at other attractions.

The metal detector is located in an area just before the loading platform of the ride. If a potential passenger activates the metal detector, a wand is used to determine what specifically triggered the mechanism.
